I know my mother has it, and so do I. It might also be on my dad's side, not sure. But the genetics are strong, to say the least. Certain things make it worse: improper hydration, improper nutrition, and exhaustion, for instance. To give an example, if you do as many push-ups as your body is capable of doing, by the end, your muscles are so weak that...yep, they begin to shake, they begin to tremble, they begin to rattle, until you can't hold your weight and collapse. THAT, I'm pretty sure, is something universal to everyone.
...Except, for me...this effect can happen at any time. At certain times, it's bad enough where my mom (who I inherited the condition from!) insists that I get a checkup, to make sure it's not something more severe, like Parkinson's. I dismiss it, in part because I don't want to waste time and money at the doctor for something that they are unlikely to confirm either way, in part because it's usually not a bad problem and only crops up every rare once and a while.
...Well, that's not true. It happens all the time, it's just that bad episodes only come up every once and a while. This effect (which I think might have a technical name of body tremors? Not sure exactly) is obviously annoying, and cause for concern in those who see it, but ultimately harmless.
...Still...all the same. Yesterday, I was trying to work on Red Hood Rider some. I did manage a panel and a half, but hindering my progress? My shaky arm was so out of control that I was unable to make a straight line with my pencil. I could barely maintain contact with the paper! The level of precision needed to draw accurately just wasn't possible.
That's never happened to me before. Admittedly...this was at something like six or seven PM, when the last meal I had was breakfast. So the lack of proper nutrition (and for that matter, hydration) causes could have come into play. Yet I can't help but be afraid that it's not going to go away.
I mean. I have to draw in moderation, given that I don't want to worsen any of the problems in my hand, like the wrist one I talked about two days ago. But if this problem persists, I won't really be able to draw at all, because of that strong interference. It's a serious concern of mine.
And it's not even gone. As I was typing this, I did an experiment. I rested my fingers on the keyboard. Then, I raised a single finger, while keeping all the others on the keyboard. (When I type, my wrists bend backward, as to allow all my fingers to be up, for rapid-fire typing. It's complicated, but I moved all across the keyboard in split seconds thanks to my high WPM typing speed.)
...And I'm pretty sure that your finger is not supposed to be violently shaking when lifted like that. When I tried to stop the shaking, the only thing that happened was other fingers started shaking, until I placed the lifted finger back down on the keyboard.
Now, for a writer, this isn't a problem. It doesn't influence the way I type at all. The trembling only happens when I'm taking specific positions, and none of those positions are relevant to typing. It may influence my handwriting, but I haven't done much of that lately. (I did notice, though, that when I tried to print out words that my writing was a lot sloppier than before on the page I was working on. This wasn't some "deterioration of quality in writing over time", which does happen given my focus on quantity over quality in writing things down. This was a case where it was physically impossible for me to make my writing look neat, and I was struggling to do what I did.)
However, as an artist, this is disastrous. This is not a problem I used to have. But it is a problem that I have. And having it, I can't make my work as well as I used to. It's really not fair. A temporary problem, I can live with. A treatable problem would be fine. A problem I strongly suspect there is no cure for, but which destroys the possibility of me improving in my art?
Very, very cruel.
